Actually, I’ve been running it for most of today. Changes seem transparent and nothing too weird has happened.
I think my theme doesn’t break… at least I haven’t seen any breakage. Here’s hoping it stays that way in the theme department 🙂
I did have a widget that doesn’t function properly anymore. Fortunately, it’s mine! Yes, the Single Bookmark Category List widget breaks in WP2.2. I’m working on a fix and it should be complete by the end of tomorrow. My apologies goes out to users of the widget.
